圆领瓣在上颌完全埋伏阻生智齿拔除术中的应用

Application of Round Collar Flap in Maxillary Completely Impacted Wisdom Tooth Extraction

目的:探讨改良翻瓣术式“圆领瓣”在拔除上颌完全埋伏阻生智齿中的应用效果。方法:选取2020年6月~2020年12月在武汉大学口腔医院口腔外科门诊接受上颌完全埋伏阻生智齿拔除术的患者70例,根据随机数表法分为观察组与对照组,每组35例。观察组采用“圆领瓣”翻瓣术,对照组采用传统角形瓣。比较两组切口缝合时间及拔牙创愈合情况。结果:观察组和对照组患者的愈合情况没有显著差异,观察组的切口缝合时间明显少于对照组。结论:与传统角形瓣相比,“圆领瓣”翻瓣术龈瓣缝合容易,线结易于拆除且不易遗漏,拔牙创愈合效果与传统翻瓣术式没有显著差异,值得在临床上推广应用。

Objective:To investigate the effects of"round collar flap"in the removal of completely impacted maxillary wisdom teeth.Methods:A total of 70 patients with maxillary impacted wisdom teeth were selected in the Department of Oral and Maxillofacial Surgery of Stomatological Hospital of Wuhan University from June 2020 to December 2020.According to random number table method,they were divided into observation group and control group,with 35 cases in each group.The observation group was treated with"round collar flap",while the control group was treated with traditional angular flap.The incision suture time and wound healing were compared between two groups.Results:There was no significant difference in the wound healing between both groups,however,the incision suturing time of observation group was significantly shorter than that of control group.Conclusion:Compared with traditional angle flap,wound of"round collar flap"is easier to suture,and the knot of"round collar flap"is easier to remove and is harder to omit.
